Relating Division and Multiplication up to 99

See how multiplication and division fact families work together up to 99, so you can check answers and solve problems faster.

What You'll Learn

Recognize that multiplication and division are inverse operations that undo each other

Build a fact family from one array, such as \( 6 \times 7 = 42 \), \( 42 \div 6 = 7 \), and \( 42 \div 7 = 6 \)

Check a division answer by multiplying the quotient by the divisor to see if it returns the dividend

Use an array or equal groups to find both a multiplication fact and its matching division facts

Apply fact families to find a missing number, such as solving \( 8 \times ? = 56 \) using division

What You'll Practice

Using arrays to complete division and multiplication sentences

Filling in missing numbers in fact family tables

Connecting division problems to related multiplication facts

Why This Matters

Understanding how division and multiplication relate helps you solve problems faster and builds number sense essential for algebra. This connection is a key strategy you'll use throughout math, from mental calculation to solving equations.
